HP Z800 Workstation - Statement of Volatility

HP confirms that the Intel-based Z800 personal workstation contains DDR RAM volatile memory (memory amount depends on the customer configuration). In addition, the motherboard, in the condition originally shipped (without subsequent modification or the addition or installation of any applications, features, or functionality), contains the following nonvolatile memory: ICH Real Time Clock (RTC) battery backed-up configuration memory (256 Bytes), Super I/O battery backed-up configuration memory (8 Bytes), LAN EEPROM (2M Bits), SAS FLASH memory (2M Bytes) and battery backed memory (256K Bits), 1394 EEPROM (2K Bits), masked keyboard ROM (2K Bytes), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128 Bytes programmable), and Serial Flash IC for System BIOS (16M Bits).
The volatile memory is cleared by removing power from the system for longer than 30 seconds. The nonvolatile memory on the motherboard is restored by following the steps below.
  1. Download the latest BIOS for this system and operating system off of the HP website.
  2. Follow the instructions on the website to flash the BIOS. Flashing the BIOS will reset it back to factory settings.
  3. Enter F10 setup.
  4. If ownership tag is set, manually clear it, save changes and exit.
  5. Re-enter F10 Setup.
  6. Set defaults and exit (this will clear passwords and any other settings).
  7. The RTC and Super I/O battery backed-up memory is cleared by removing the battery found on the motherboard, allowing the board to sit for longer than 60 seconds, and then replacing the battery.
The LAN EEPROM is inaccessible to the consumer via any publicly available tools. There are programs used by HP in manufacturing and research and development that allow access, but these are not available outside of HP. The embedded LSI 1068e SAS controller flash ROM can be read, written, and erased via a firmware and BIOS utility SASFLASH.exe available in the latest softpaq release on the HP website. For the 1394 EEPROM, there are applications such as OHCIROM.EXE which allow access; HP does not provide this utility, however. The DIMM SPD EEPROM is not readily available to the consumer, however there appear to be tools publicly available to read and write this part. To eliminate the possibility that it could contain sensitive information, remove the DIMMs or use one of these tools.
